Just yesterday, I replaced the smart thermostats on my radiators with old-fashioned manual ones, and removed the window sensors, control hub and everything else associated with it. The whole eQ-3 ecosystem will be shut down soon anyway, and replaced with a full-scale intelligent house-type product line.
I have ordered new thermostats that are electronic and support daily/weekly schedules, but have no networking aside from Bluetooth, which you have to manually turn on via a button on the thermostat, if you want to make changes to their programming.
Aside from that they function more or less like the good old manual thermostats, you turn a dial to select the temperature you want, but they display the selected temperature in degrees instead of a scale from 1 to 5, and they automatically turn down the heating if they sense a temperature drop when you open the windows to air out.
Intelligent but not "smart" thermostats. If the app disappears for some reason or you just don't want to use it, they will still function just fine as an improved version of the old-fashioned manual thermostats. According to the manufacturer, they also calibrate themselves to know when to turn on and off to match your programmed schedule, based on how quickly your house heats up and cools down, and something about finding the exact position at which your radiator valve opens, for more precise control. Nifty stuff and it still doesn't require an internet connection or a nebulous cloud account.
